Definitions

  • first transmission device and/or the second transmission device it is very advantageous for the first transmission device and/or the second transmission device to have at least one gate and at least one driving device interacting with the latter.
  • a “gate” is also an element driving a driving device, even though no or at least no significant relative movement takes place between the driving device and this element.
  • the second control element is acted upon by spring force in a bistable manner in the direction of an opening or a closing position.
  • the second control element is therefore acted upon by a force in the direction of the opening or closing position, in which case, for example, during actuation starting from the opening position, first an actuation takes place against the (decreasingly effective) spring force; then a neutral dead center is reached in which the spring force is not active in the opening or closing direction, and then, as a result of the spring force, a “snapping over” takes place in the direction of the closing position.
  • the bistable control element will act correspondingly.
  • the second control element can expediently be displaced in a dead-center-overriding manner between the opening position or a closing position.
  • the second transmission device preferably includes transmission elements having play and a force-type connection which changes as a function of the actuating direction, so that a hysteresis is achieved.
  • an actuation of the second control element is therefore obtained caused by the spring force while passing through the play, independently of an actuator movement.
  • a correlation of movements between the actuator and the control element exists that is different than during a closing movement.
  • FIG. 2 c is a schematic view of an example of a valve arrangement having an actuator, an lift valve and a flap valve, the lift valve being open and the flap valve being closed;
  • FIG. 6 d is a schematic view of an example of a valve arrangement having an actuator, a lift valve and a bistable flap valve, the flap valve being behind the dead center in the opening position;
  • the exhaust gas recirculation device 140 has an inlet 146 on the internal-combustion engine outlet side, an outlet 148 on the internal-combustion engine inlet side and two parallel flow paths 142 , 144 extending between the inlet 146 and the outlet 148 .
  • An exhaust gas recirculation cooler 150 for the power-increasing cooling of recirculated exhaust gas is arranged in the flow path 144 .
  • the flow path 142 parallel thereto forms a bypass with respect to the flow path 144 and is used for bypassing the exhaust gas recirculation cooler 150 .
  • the actuator 202 is an electrical rotary drive; however, as required, a hydraulic or pneumatic drive may also be used.
  • the actuator 202 is non-rotatably connected with a fork-type transmission element 204 .
  • the transmission element 204 has longitudinal guides 206 extending in the axial direction of the lift valve.
  • the actuator 402 is an electrical rotary drive; however, as required, a hydraulic or pneumatic drive may also be used.
  • the actuator 402 is non-rotatably connected with a fork-type transmission element 404 .
  • the two ends 403 , 405 of the transmission element 404 are used as a “gate” for taking along the driving devices 408 or 420 .
  • the driving device 408 is assigned to the rotary mushroom valve 412 ; the driving device 420 is assigned to the rotary mushroom valve 424 .
  • Both rotary mushroom valves 412 , 424 are acted upon by force in the closing direction by way of a spring 416 , the spring 416 supporting itself on the driving device 408 on the one side and on the driving device 420 on the other side and thus acting upon both driving devices.
  • the actuator 602 is non-rotatably connected with another, pointer-type transmission element 618 .
  • the actuator-side end of this transmission element 618 is connected with the actuator axis; the other end has a driving device 620 .
  • This driving device 620 corresponds with a transmission element 622 which can be swiveled about an axis at least approximately parallel to the shaft 610 of the lift valve 612 and at least approximately rectangular with respect to the actuator axis.
  • the swiveling axis of the transmission element 622 simultaneously forms a shaft 630 of the flap valve 624 with which the transmission element 622 is non-rotatably connected.
  • the axis of the shaft 630 is situated maximally away from the axis of the spring 628 , whereby the spring 628 exercises a maximal tension force component upon the transmission element 622 in the rotating direction in the direction of the respective end position.
  • the axis of the shaft 630 coincides with the axis of the spring 628 , no spring force component will act upon the transmission element 622 in the rotating direction in the direction of the end position. This position is called the “dead center”.
